Imagine a world where we don't have to plug anything in. Your phone, laptop, tablet and headphones are constantly being topped-up whenever they're placed on an inductive surface, so that when you take them out with you into the wider world, your devices are always brimming with battery. Step-by-step, it's what we might be moving toward, if the industry lobbying group The Wireless Power Consortium gets its way. The group's long-in-development wireless charging technology, Qi, is now getting a considerable power boost, which means it will be able to charge more smartphones faster, as well as tablets, which were previously too power hungry for it. While this a big step forward for Qi, and may lead to wider adoption for the fledgling charging standard, there are other barriers still standing in the way on the road to a wireless power utopia.
